It’s kind of a moot discussion as I highly doubt this would ever change, but whatever.
The way I see it total kills always need to equal total deaths, this means they must occur at the same time, so the options for when these change are:
a) When a player is downed
b) When a player is downed, but reversed when a player is revived
c) When a player is gibbed
B would just downright piss me off, I kill a guy, I get credited with a kill, he gets revived, I get a kill taken away from me, no thanks, so ruling this one out.
The issues of going with C are that the most intense part of a duel is right towards the end, so is also the most satisfying time to receive the kill, I also suspect it would increase the number of “kill steals” because if someone new arrives mid-duel they’ll normally start shooting at the guy already engaged in the duel, rather than the kill stealer hiding in the corner, even if you down one of them you wouldn’t have time to gib before needing to engage the second guy, leaving the kill stealer free to mop-up after you.
The benefits of C are what, a slightly better KDR if people don’t gib you, which they will be doing now much more, in public anyway, because they’ll no longer be receiving the kill for downing you, meh, don’t really care about KDR, it’s just a number, more interested in the satisfaction of getting credited with the kill when it matters.
That leaves A, it happens at the duel climax point, credits more accurately the true “killer”, contains a greater level of “what the player expects should happen”, is more widely favoured by players (judging by this thread only mind you); this leaves me thinking the current implementation is fine as is.
On a side note, I’d also be interested to see gibs and assists also being displayed to the player on a per game basis as well.
